Hello Bernd,
I just installed the currently downloadable trial version of KBasic "installer_kbasic_professional_windows.exe" on my ASUS R1F tablet notebook, running WinXP Professional Tablet Editions 2002, SP3. The installation went smoothly, but the IDE fails with a MS Error, after selecting the "Trial" button, and choosing the "Help Preference".
The error message says "kbide.exe has encountered a problem and needs to close". The detail says "AppName: kbide.exe", AppVer: 0.0.0.0, ModName: qtgui4.dll, ModVer 4.4.0.0, Offset 0050b56".
I installed the same binary on a computer at work with no problems (HP DC7700, WinXP SP2), so it must be specific to my machine.
Any ideas?
