I wanted to set up the Arduino Uno to program from Atmel Studio 7 and followed guides on the web.
Atmel Studio 7 (Build 7.0.790) kept crashing with error CLR20r3 originating from exception thrown by mscorlib. On further monitoring using DebugView the AS7 was attempting to open a file in appdata that was generating an unauthorized access exception. I restarted Atmel Studio 7 as administrator and this cured the problem. Thought this might help others who experience something similar

Yea, that's not the best idea. If it runs amok, it could cause damage almost anywhere. It also becomes a security vulnerability.
You may have some AS7 installation problem (no surprise with this product) or a Windoze user account issue (not unbelievable either). Perhaps some files were copied around while logged into an admin account? They may have retained their ownership and permissions, which would cause problems when they are accessed from a limited user account. Perhaps using AS7 while logged into admin may have left these kind of landmines for limited user accounts?

thanks for the response, I actually have two pc's running this software, one has no issues at all and is perfectly stable, the other kept crashing with AS7. I removed all .net files and reinstalled the latest versions to no effect, I removed earlier versions of Visual Studio, again with no effect. After re-installing AS7 multiple times and tracing the crash to the attempted file access in appdata, it was a "maybe this will work" last ditch attempt to get the system running. I don't normally run programs as admin so whilst your comments are helpful, I have no idea why it is critical for this program on this PC. I appreciate your advice on potential harm that can arise from running in this mode, cheers.
