  Permission Denied -Unable to write file Reply Contact  Hello everyone, i receive this error: System.ApplicationException: MWMCR::EvaluateFunction error: Error using ==> save Unable to write file nYFBRA2N.mat: permission denied. My question is: where can i change the permissions to write/save files in IIS, or this is a problem with sql server where i have my database, if so where can i put the permission to write? Another question is:  In the "Turn on User Account Control (UAC) to make your computer more secure" i click to unselect the "Use User Account Control (UAC) to help protect your computer", and then i could run my project with visual studio when i was building the web site, and the error dissapear , but when i put my web site in IIS, because i finish of building the web site, doesnt work anmore, and i get the same error in past. I have vista, and IIS 7 Thanks

  Re: Permission Denied -Unable to write file Reply Contact  Hi, xtinction84 Only a user with highest permission can change files in folder "C:\Windows\System32\" and its subfolders. Therefore, place you file in any other folder but don't in "C:\Windows\System32" After doing this, if you still can not write the file, you can alter the identity of IIS application pool from Network Service to Local System(or Administrator). This action is only for test, please use Network Service when your website go to production server.
