Hi I always get the error that AnsysWBU.exe encountered a problem when I try to solve a static-mechanical model.<\/p>\n

\"\"<\/a><\/p>\n

I am using the 2023 R2 student version.<\/p>\n

I have reinstaled Ansys several times using admin rights.<\/p>\n

I start workbench as admin.<\/p>\n

I’ve tried creating several simple models using tutorials, but allways get the same error as above when trying to solve.<\/p>\n

Also I’ve tried Opening CMD as admin and typing:<\/p>\n

regsvr32.exe ole32.dll
regsvr32.exe atl.dll
regsvr32.exe oleaut32.dll
regsvr32.exe scrrun.dll
regsvr32.exe jscript.dll
regsvr32.exe vbscript.dll<\/p>\n

as well as renaming the Ansys folder in %temp% and %appdata%.<\/p>\n

I am using Windows 10 Pro with:<\/p>\n

AMD Ryzen 5 3600X 6-Core Processor, 3800 MHz, 6 Kern(e), 12 logische(r) Prozessor(en),<\/p>\n

\n
NVIDIA GeForce RTX 2080 SUPER, (newest drivers installed)<\/div>\n

 <\/p>\n<\/div>\n

That’s one model:\"\"<\/a><\/p>\n

 <\/p>\n

When analysing the diagnostic file I get:<\/p>\n
