@Haute:
I just tried different things:
1. Installation of GM15.1.9-64bit (last version of today); patched using PATCH_GM_15.1.9_64BIT.rar ==> works fine!

2. Installation of GM15.1.9-32bit (last version of today);patched using PATCH_GM_15.1.9_64BIT.rar ==> DOES NOT WORK!
- Program seems to be unchanged; works like unpatched version;

3. Installation of GM15.1.9-32bit (last version of today);patched using Global.Mapper.v15.1.8.Patch.REPT.zip ==> DOES NOT WORK!
- give some strange error-messages and terminates by itself;

Anybody any idea for 32bit-version?
