Variable %SrcDir% is erraneous when uninstalling

[HayoOellrich]

Hi ! I am using SF 6.0.0.4.

I detected a strange effect with variable %SrcDir%:

My install uses a bat-file, which resides on a network share (on Windows NT), its UNC notation is
\\nt0003\Inventar\inst.bat.
Variable %SrcDir% stores the path.

When executing the install, the bat-file runs ok. A message box says
"Execution of \\nt0003\Inventar\inst.bat ended".

When executing the uninstall (where I also use the bat-file), I have a problem. The message box says
"Execution of \t0003\Inventar\inst.bat ended" ???
SrcDir = \t0003\Inventar
SrcDrv = \t0003

Please help!
