The software license check out failed. Error 20.

[Titaus]

Hey all,

I have a problem that I am hoping someone here can help me with. I was reading others with similar issues, tried messing with flexnet, and cascade to no avail.

While working in 3d max today, I get a BSOD related to my video drivers needing to be updated. I restarted my computer, and upon logging back into windows, and starting 3d max, I get the error message-

"The software license check out failed. Error 20."

I can't get back into 3d max, repair, or reinstall in windows control panel. When I try to uninstall, I get the message(s)-

"1: 5 2: Failed to install/uninstall the anchor service. The Service is in use, Please try again later 3: 1002" and
"1: 5 2: Failed to install/uninstall the anchor service. 3: 1002"
It then tells me that the product failed to uninstall.

What can I do?

My computer is-

Intel i7 2600

Gigabyte  Z68X-UD4-B3 motherboard

G Skill 8gb DDR3 2133 RAM

EVGA Geforce GTX460 2048mb video card

Windows 7 Professional 64 bit OS

Looks like some file corruption.

If you have no other Autodesk 2010/2011/2012 products, please delet the license files (c:\programdata\flexnet\adskflex*.*)

and try to uninstall.

If it fails, you might have to manually clean up the installation using a 3rd party tool.
