I am having a problem with a computer running Windows 7 on our domain. This computer will not run internet Explorer correctly, for example using citrix addon.

Also when I tried installing .exe's they would give an error 2349. Another thing is when I download an exe from Internet Explorer 9, they would be .exe but cannot be run and not shown as executable but as file. If I run exes as Administrator or internet Explorer as Administrator, they work as intended. Any ideas?

Open Registry Editor as that user and check whether HKCU\Software\Classes\.exe and HKCU\Software\Classes\exefile exist; if yes, delete them. (Be careful -- don't confuse it with the system-wide HKLM\Software\Classes.) – grawity Sep 9 '11 at 13:03
"This computer will not run internet explorer correctly, for example using citrix add-on" Can you please give us some details on what doesn't work? – uSlackr Sep 9 '11 at 13:22

Sounds like there are some good security restrictions in place. This may be expected security behavior.

Agreeing with uSlackr, it sounds as if Windows is (correctly) configured so that non-Admin users can't install software or run untrusted (downloaded) binaries. Again, this is correct behavior, not a problem. You should install software only as Admin, and only after taking due care.
