I have an extension that writes to bin directory of ArcGIS installation. At 931, with power user rights, it works fine but at ArcGIS 10, it doesn???t allow copy of the dll's to C:\Program Files\ArcGIS\Desktop10.0\Bin folder. As local admin, it works fine and copies all the files properly. It seems like something has chnaged at ArcGIS 10 that is preventing this. I am looking for some feedback on possible options to resolve this issue.
This is more than likely an operating system issue rather than an ArcGIS 10 issue. Typically, users do not have Write privileges on the Program Files folder. Therefore, applications should not write to folders under Program Files. You will need to write to another location, such as the user's profile application data folder or the common application data folder. Older operating systems, such as Windows XP may not have this limitation but you should write your application to be as OS neutral as possible.
