Designer crashes at startup

Hi All,

After installing DS Client on a Windows 10 PC, I launch it and it starts to load then ends before the login window opens. In the application log Windows is logging this:

Faulting application name: AL_Designer.exe, version:, time stamp: 0x5cbd8e00
Faulting module name: ucrtbase.dll, version: 10.0.18362.387, time stamp: 0x4361b720
Exception code: 0xc0000409
Fault offset: 0x000000000006db8e
Faulting process id: 0x2e94

I have previously installed the same client version on another Windows 10 laptop and that works. I have compared the size and datestamp of the ucrtbase.dll on the two machines and they are identical. I have also tried installing all the same versions of the MS Visual C++ redistributables as are on the machine that is working, and no luck.

Any ideas ?

Thanks Ajay, however I found a SAP KB article with a workaround via the SAP forum.

The workaround is as follows:

Take a backup of %LINK_DIR%\bin\CreateDemoCerts.bat on Windows or $LINK_DIR/bin/ on UNIX.

Edit %LINK_DIR%/bin/CreateDemoCerts.bat on Windows or $LINK_DIR/bin/ on UNIX and change the value of VALIDITY_DAYS from 10950 to 9125.

Take a backup of folder %LINK_DIR%\ssl on Windows or $LINK_DIR/ssl on UNIX.

Remove all the existing files under %LINK_DIR%\ssl\server on Windows or $LINK_DIR/ssl/server on UNIX.

Regenerate SSL certificates using %LINK_DIR%\bin\CreateDemoCerts.bat on Windows or $LINK_DIR/bin/ on UNIX.

If you are on server machine then Recreate/resync the job server. For Designer client machine, just run designer.

I had the same issue when installing 4.2 SP13 on Windows Server 2016. I used the same KB instructions in the post above.
