It is used to secure the testing computer, securely locate, open, write, and return encrypted exams and preserve the integrity of the exam content and process. SofTest operates on Windows XP, Vista and Windows 7 platforms and is not dependent upon the installation of any third party programs, dedicated servers or server software. Candidate exam files are downloaded and answer files auto-uploaded via the Internet using SofTest. Internet connectivity is ONLY required to download and upload exams. Internet Connectivity is NEVER required DURING an exam. During a SofTest secure exam, SofTest prohibits normal behaviors including: Windows Desktop Icons, Task Bar Availability, Power Management, Desktop Wallpaper and Screen Savers, Task Switching (Alt-Tab behavior), Start Menu and Control-Escape behavior, Task Manager Access (Ctrl-Alt-Delete behavior), It forces closure of all open programs and windows not associated with the exam process, Windows clipboard control, and Prevents creation of any new windows or processes by the user or any pre-existing scheduled activity (e.g. reminder programs, etc.). SofTest blocks the use of virtual programs and prevents the running of select Windows services that could be used to breach security. (i.e. VirtualPC, VMWare, NetOP, Multiple XP users, etc.) Exam files opened are opened exclusively by SofTest and cannot be viewed by any other user. Page 3 of 36 version 5.0.0 Administrator Handbook ExamSoft Worldwide Minimum Specifications for Testing Computers SofTest may only be used on a PC (Desktop or Laptop).

Page 4 of 36 version 5.0.0 Administrator Handbook ExamSoft Worldwide SofTest Use Summary 2.1. Installing SofTest SofTest may be installed using our MSI Installer (page 8). Installing SofTest REQUIRES Administrative rights to the local computer. Using SofTest does NOT REQUIRE Administrative rights. 2.2. Taking the Mock Exam To ensure SofTest has been properly installed, after installation reboot the computer and log into Windows using a user account with the same level of permissions used by your exam candidates. Next, using the User ID and Password combination assigned to YOU by ExamSoft, launch SofTest, download a copy of the Mock Exam, complete it and upload the answer file. The Mock Exam simulates the exam taking process the exam candidate will encounter on exam day. Taking the Mock Exam will identify any underlying issues with Intranet firewalls, proxy server settings or permissions (see Permissions page 31). 2.3. Taking Real Exams Once the Mock Exam has been completed, SofTest is ready for use on exam day. EVERY exam candidate MUST download their copy of the exam using the unique ID and Password combination assigned to them. DO NOT DOWNLOAD one exam file and then copy it to multiple machines. DO NOT USE another exam candidates ID and Password to download an exam file for use by someone else. EVERY exam candidate MUST USE the ID and Password provided to them to download a copy of their exam. 2.4. Uploading the Answer File SofTest will automatically upload the answer file after the exam has been closed provided the exam candidate logs back into Windows. Accordingly ALL exam candidates MUST log back into Windows for SofTest to auto return the answer file. DO NOT uninstall or re-image the testing computer without preserving the directory that contains the student’s backed up exam file. The location of the backed up exam is: c:\program files\examsoft\softest\bak.

SofTest doesn’t boot into Secure Mode Upon selecting the exam file and clicking the ‘Begin Exam’ button SofTest should reboot the computer into secure mode. Secure mode works by modifying the Shell registry key so that SofTest runs instead of Explorer. If SofTest doesn’t reboot into secure mode, and the user reboots into the normal desktop environment, then check to ensure the user running SofTest has read/write permissions on the following registry key. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon Page 31 of 36 version 5.0.0 Administrator Handbook ExamSoft Worldwide 13.4.

Also, if your site uses a caching proxy server then contact your IT Group and have them clear the temporary Internet files for the proxy server. 13.6. Error Message(s): when Starting an Exam If you receive the following error(s) then either there is a security program locally installed on the computer preventing SofTest from writing to the registry or the user doesn’t have the necessary privileges (permissions) for SofTest to write to the registry. If no security software is present then please see item 8.2. Permissions. Error: SofTest cannot open your exam. This may be the result of Anti-Spyware running on your computer. Disable or remove any Anti-Spyware and re-open SofTest. If this fails contact ExamSoft Client Support or your IT Department. Error: Unable to start this exam. Failure to write shell information to the registry. 13.7. Error Message: Unable to Establish an Internet Connection If you receive this error then you either have a locally installed Firewall preventing SofTest from accessing the Internet or your companies, school’s, Intranet Firewall needs to be setup to allow SofTest to communicate to www.examsoft.com over port 80. 13.8. Error Message: Type ‘13’ Mismatch If you receive this error when you are trying to register softest then you either have a locally installed Firewall preventing SofTest from accessing the Internet or your companies, school’s, Intranet Firewall needs to be setup to allow SofTest to communicate to www.examsoft.com over port 80. 13.9. ISA Server Firewall Although SofTest successfully downloads and uploads exams even in the presence of an ISA Server Firewall, in some cases, the ISA Server software miscalculates the final file integrity check of the answer files following the upload. Believing it to be a corrupted file, SofTest deletes the uploaded file. This can occur even if the ISA Server software is instructed to permit ALL traffic to the examsoft.com domain. As such, if you utilize an ISA Server Firewall, it might need to be disabled on the testing computers used during your exam cycle(s). Page 33 of 36 version 5.0.0 Administrator Handbook ExamSoft Worldwide 13.10. Mid Exam Restart ALL exam files are single use files that may only be opened and closed once. In case of computer freezes or power outages SofTest manages exam recovery. In such an occurrence, security is maintained and the answer file is recoverable when the computer is rebooted. Step 1 – Have the Candidate reboot the computer. Step 2 –If the candidate used a unique username/password combination to log into Windows, use that same combination to log back into Windows again. Step 3 - Upon recovery from a computer freeze or power outage the following message is displayed. These are the only 2 options available. Access to the computer is blocked until one of the options is selected. See Figure 36 below. Figure 36 When ‘RESUME’ is selected, the exam file is reopened and access to the exam at the point of interruption is automatically restored. If the exam is timed, the timer is paused at the point of interruption and restarts when the exam is reopened. The Exam Taker is not penalized for the time elapsed while the exam was interrupted. When ‘Exit’ is selected, the answer file found will be closed, a final save is made and encrypted answer files are created. The exam can no longer be re-opened. Page 34 of 36 version 5.0.0 Administrator Handbook ExamSoft Worldwide 13.11. Manual Upload (Auto Upload Does Not Work) If auto-uploading the answer file fails, the Exam Taker is given another opportunity to auto upload or to manually upload. See Figure 37 below. Figure 37 To use the Manual Upload option, select ‘Manual Upload’, see Figure 37 above. SofTest will automatically launch a web browser which will bring up the Manual Upload page. Follow the on-screen instructions to manually upload the answer file. See Figure 38 below.
