If netframework 2.0 SP-1 shows up in add-remove and 2.0 does not, do you need to install the 2.0 version also or is 2.0 sp-1 a rollup which includes 2.0. Reason? I seem to be having a problem with SuperAntiSpyware updates and also some video problems with my GeForce 7600GT AGP. I tried googling for the answer, but it wasn't clear. Overall, if you install a SP, it seems to include the original version. Is there a way to check to see if your version of NetFrameWork is corrupted? I have several instances of NetFrameWork 1.1 also Running Win2000Pro SP-4. I tried running netfx_setupverifier.exe but I get an error message relating to WINNT\System32\advpack.dll while trying to install it. My advpack.dll version is 6.00.2800.1106. Could that be a problem? Thanks, Buffalo PS: Is there a way to get SFC working? I tried inserting my Win2000Pro cd when trying to run sfc, as instructed, but it says it is the wrong CD. The CD player I originally used to install the system is no longer working and my newer CD/DVD writer is a different letter. Could that be the problem?
