Crystal Reports .NET Error - "Access to report file denied. Another program may be using it."


I encounter this problem several times, the way to get around this is to give "Everyone or Network Service " permission to "C:\windows\temp" folder. I gave everyone on my development box just for convenient.

I hope it will help you solve the same problem as I had. 

 

Here are some references:

"It is enough to give read, write permission to NETWORK SERVICE user. crystal report create a temp file with guid for name in windows temp folder, so it needs write permission to the disk to make create that temp file."

Check your permission on temp folder under windows folder. I don't think windows will give "network service" or "everyone" write permission by default.

the same problem I had been encounted.YES,you said that: make "network service" or "everyone" Account can access the temp folder.
but can raise them into the user group 'IIS_WPG'.

it's better to give write permission to Network service.coz iis 7 & iis 7.5 application pool by default will use"network service" account :)
