There's no parental controls installed, CORRECT? Does the computer do this with all programs you try to install, or just one specifically?

Flamelol it is administrator window, ofcourse there wont be parent controls,
Yes it does to all the window i try to installIt just means your account isnt setup for adminstrative privlages to fix it use a administrator screen name or ANOTHER admin screen name open up your user accounts and adjust the settings to give you full access. Did you check to make sure your account wasnt LIMITED or guest. Windows 2000 has alot of OPTIONS to chose from so im just judging by there. If you have only one screen name there then you can use safemode. Safemode should be able to show the user screen name of Administrator.. hope it does it did for em once. and just use the same pass as the orginal pass you set up with your account with and if it doesnt have a pass then you should be able to get in easily.

If one screen name is messed up delete and recreate it of course if you delete and recreate your scrren name then all the orginal settings on the other accounts will be deleted alsoAhem... The administrative account CAN have parental controls on it. There obviously isn't on your computer. Are there other users on this computer?

Flameyes there 1 more person use the computer and she use administrator window too.
Im 100% no parent control
100% my window login is a administrator
i didnt get from you anything  (Windows98)
i did wat u said but i dont know where the setting is   :-?
can u show me each step it would be easier  ( im using xp window)
thanks alot broI think my only way i would fix this is System Restore
Or this:
Try updating permissions
1. Run regedt32.exe (has to be regedt32 NOT regedit)
2. Select the window HKEY_LOCAL_MACHINE ON LOCAL MACHINE
3. Select the SOFTWARE key
4. Click SECURITY (or PERMISSIONS) from the menu bar (under the "Edit" menu)
5. Click PERMISSIONS
6. From the Security section, highlight USERS
7. Check the option FULL CONTROL
8. Click APPLY
9. Click the ADVANCED button
10. Highlight USERS from the ?Permission Entries? section
11. Click VIEW/EDIT
12. From the permissions section, uncheck the DELETE option from the ?Allow? column
13. Click OK
14. Click APPLY before continuing to the next step
15. Check the option ?RESET PERMISSIONS ON ALL CHILD OBJECTS AND ENABLE PROPAGATION OF INHERITABLE PERMISSIONS?
16. Click APPLY again
17. Click YES at the security dialog warning box
18. Click OK to the message about registry editor not being able to set permissions on some keys
19. Click OK back at the access control settings for the SOFTWARE key
20. Click OK back at the permissions for SOFTWARE dialog
