Hello, I have been having a conflict between WRSA and VIPRE now for the last several WRSA builds. I finally have a pattern that may give enough information to troubleshoot the conflict. Here is what I know: If VIPRE is already installed and then I install WRSA, both programs work fine. If WRSA is installed and then I install VIPRE, VIPRE has lockups, GUI will not open, and random BSOD's on boot. All of the program components for VIPRE are always marked "monitor" under System Tools>System Control>Control Active Processes. Changing these to allow helps somewhat but does not completely solve the problem. With VIPRE installed first, WRSA second, and with both working fine, and then a program update is available for VIPRE, Vipre again will not work properly and has the same errors noted above until I uninstall and then reinstall WRSA. After this is done, all works properly. So in conclusion: As long as WRSA is the last program installed, then both VIPRE and WRSA both will work properly and if VIPRE is installed last the problems occur. Whenever doing program updates for VIPRE, it is best to uninstall WRSA first, do the update, and then reinstall WRSA. You can also do the VIPRE update first, then uninstall and reinstall WRSA, but in this scenario you will have to put up with conflicts until you get WRSA uninstalled/reinstalled. I am on Vista Home Premium 64 bit. As I say, this has been happening for several builds now and I have just now figured out the exact symptoms. I thought I would start with WRSA as far as troubleshooting since WRSA is made to be compatible with other security apps. If I need to I can also let Nick at GFI know about this thread if the problem appears to be on his end. Thanks in advance for any help with this conflict.
