It worked on me ... atm i got fraps 2.8.2 running fine on my pc
what i did:
1. remove old verion of fraps / trial
2. restarted pc
3. start regedit and search for nZgFQGQhfU (if u got it) and delete its CONTENT (not the main folder)
4. delete folder “HKEY_LOCAL_MACHINE\SOFTWARE\Licenses" (note i dont have anything licenced installed so u might have to search for the right key if u have licenced products installed in your pc)
5. search register for "fraps" and "fps1" and delete every result u get
6. delete "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\RFC1156Agent \Currentversion\parameters" the parameters folder
7. delete "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\RNG" the rng folder
8. delete all files u can from "C:\Documents and Settings\yourname\local settings\temp"
9. delete frapsvid.dll located in "c:\windows\system32" folder
8. dowload and install MSCOMCTL.OCX file and Trial-Reset (if links dont work use google)
9. run Trial-Reset and search for "protectors" menu, select armadillo and select scan
10. right-click every search result and select clear
11a. If u got no problems deleting the search results just install ur FULL verion of fraps and enjoy
11b. if u get acces denied on any of the armadillo registery keys when tried to clear, go to regedit again and search for the key in question (u can see the root/location in the Trial-Reset search results)
12. right-click the key in question and select "rights" (7th option) and check the boxes: "full rights, read and special rights" click ok
13. now u can delete the whole key in question
14. Re-scan with Trial-Reset and if u get no results from armadillo install ur FULL verion of fraps and enjoy
ps. im foreign so there might be some speling mistakes ^^ but i hope this helps u alot
