PSS®E Windows Compatibility

PSS®E is compatible with Windows 7 from version 33.1 forward

Versions 33.0.0 and lower of PSS®E are not supported on Windows 7, but users who wish to try it should be sure to set user access controls appropriately.

  • From the Control Panel, go to "User Accounts & Family Safety". Click on "User Accounts". Click on "Change user account control settings". Drag the slide bar down to "Never notify". Click "Ok" and then "Yes". Restart your computer.
    Note that if you performed the above step before installing PSS®E then you should not need to perform the following 2 steps involving regsvr32.

  • After rebooting, click on the "Start" button. In the field that says "Search programs and files" type "run" and press "Enter". In the "Run" dialog box, type:
    regsvr32 "c:\Program Files\PTI\PSSExx\PSSBIN\teechart7.ocx"
    where PSSExx refers to the version of PSS®E, e.g. PSSE32 for PSS®E version 32.
    Press "Enter". You should see a message that the process succeeded.

  • If you purchased the Transmission Line Constant option, then repeat the above step, this time entering the following text in the "Run" dialog box:
    regsvr32 "c:\Program Files\PTI\PSSExx\PSSBIN\ALineProp.ocx"
    where, again, PSSExx refers to the version of PSS®E, e.g. PSSE33 for PSS®E version 33.
    Press "Enter". You should see a message that the process succeeded.

  • If your copy of PSS®E is installed in a location other than the standard c:\Program Files\PTI\PSSExx, then replace the path in the above regscr32 commands with your path.

  • After you successfully register the 2 files mentioned above, you can change the User Access Control setting back to the "Default" setting.

  • In addition to User Access Control, you should change the PSS®E shortcut to run in a "Compatibility" mode. Do this by right clicking on the PSS®E 32 shortcut, choose "Properties". Select the "Compatibility" tab. Check the box to "Run this program in compatibility mode for:" and choose "Windows Vista (Service Pack 2)" or "Windows XP (Service Pack 3)".
    If you experience problems running any of the other PSS®E-related utilities programs, try changing the compatibility mode on them as well.

  • PSS®E is not certified for 64-bit operation. PSS®E is not a 64-bit program. There is little, if any, performance advantage to running PSS®E on a 64-bit machine. It appears that it does run correctly on 64-bit systems although there are some special considerations for users with network locks.
