my system is windows2003 ，new installed。
install .net2.0 3.5sp1 and patch
Encountered a problem and needs to close
Install .NET 2.0 or higher, KeePass 2.x requires it. NET 2.0 was not distributed with Windows 2003 until R2.
Otherwise you must use KeePass 1.x.
Windows 2003 is the server version. Is that what you are running?
What is the detail from the error message?
