I found the best solution to this problem
What you need to do is go to event viewer - System Log.
Look at the error it will look something like that

The machine-default permission settings do not grant Local Activation
permission for the COM Server application with CLSID
{671E00F1-44C3-401E-9E33-8E5E585F26BE}
to the user WK01SF78\IUSR_XXXXXX SID
(S-1-5-21-2939499473-2795378169-3261179525-1005).  This security
permission can be modified using the Component Services administrative
tool.

Open Component Services and Under DComConfig(Windows XP) find
componnent {671E00F1-44C3-401E-9E33-8E5E585F26BE} and under Securities
give "Everyone" full access (Under every tab)

That solved my problem
