hello Jude,
thank you for your reply. Our server was already patched to PL 37, although i think i used the patch without AWUS. Now i applied SAPSETUP90P2SP00_37-20008539 to the server. Patch was recognised and installed correctly. Check Server Option shows green but the installation of AWUS still terminates silently with same error logs as written above.
If there are some files missing or have false file version, should this not be detected by the server check?
