Why so much trouble opening files

I installed windows 7 ultimate….I am having so much trouble opening up apps I download from here with winzip and winrar….any suggestions on whats wrong?
Alot of them say file corrupt etc……. thanks for any info in advance!!!!
Answer #1
Maybe the files are not complete..Check the size of the archives..
Or maybe corrupt..If so..Download again..
Answer #2
What the Lion says and:
The newer winrar 5 archive is not backwards compatible with winrar 4 – rar files from v5 can’t be opened with v4.
So, you might have v4 and are downloading v5 rars??
Also, to extend what said:
If you download s multi-volume archive all the archives but the last should be exactly the same size.
E.g – Directory of D:\Downloads

If any one of those first 7 is not that size then the file is corrupted.
You might be able to re-download just that one and be fine… or it might be corrupted from before the upload, in which case you’re SOL and need to look elsewhere for the program.

I just dont understand it…..Alot of apps I get off of here work on my XP puter but not windows 7….I thought they might have something on windows 7 to block them?

It very much depends (sorry).
Some programs just don’t like W7 – you need compatibility mode set to XP.
Some programs need newer visual C++ dll files – you can grab them from MS, visual c++ runtimes (get both 32 bit and 64 bit versions if you have x64 windows).
It might also be a protection – UAC in W7 does block some programs.
