I've had this peculiar problem for the last couple of days:
2 programs - SpywareBlaster (SB) 3.0 (yes, the new version) & GetRight (GR) 5.1 - refuse to open or run.
If I click on their icons or their .exe files in Program Files the outcome is the same. The PC seems to be opening them (hourglass mouse) but a few seconds later (or even minutes) they do NOT open or run.
Sometimes they appear to be running in the background (they appear in the Ctrl+Alt+Del Close Program window) but their windows or interfaces do not display.
If I reinstall an older version of SB it works but when I try to update it, I'm prompted to download the new version. The old version will not allow me to download the latest definitions.
If I uninstall/reinstall GR I have the same problem.
GR problems started 2 days ago, SB a day ago. SB problems ever since I downloaded & installed the new version. Have not changed anything else in the last few days. Reinstalled Visual Basic as one SB fix suggested.
My PC: Win98se. Scanned for viruses, ad/spyware, scandisk, etc., etc. No problems.
Please let me know what to do to rectify it? Any suggestions/links most welcome. Ta, G
