Basically, the avast tray icon is working, but when i actually try to run the scanner, it shows the loading thing with the pointer, but it never opens the program.
About the "usigetskin failed" issue, if the repair does not solve it:
You will have to register ACTSKIN4.OCX
Follow the instructions:
Select START -> RUN...
Enter the following command:
If you have Windows NT or 2000:
C:\WINNT\SYSTEM32\REGSVR32.EXE ACTSKIN4.OCX
If you have Windows 95, 98 or ME:
C:\WINDOWS\SYSTEM\REGSVR32.EXE ACTSKIN4.OCX
If you have Windows XP:
C:\WINDOWS\SYSTEM32\REGSVR32.EXE ACTSKIN4.OCX
Press OK (or Enter).
A message saying that the file was successfully registered should appear...
As a workaround, we may disable skinning in avast - that should solve the problem. For some reason, ActiveSkin (the 3rd party library avast uses for skinning) does not seem to be working on your system.
To do that, open the file <avast>\data\avast4.ini, look up the [UserInterface] section, and add the following entry:
StartWithSkin=0
