After trying to install the new 2023-1 on a clean install of Windows 11 Pro (ARM64) in Parallels, there was still an error preventing the start of Allplan. The issue is conncted to msvcp140.dll (part of the Visual C++ Redist package) The problem is, when installing VC++ Redist x64 version, the installer automatically detects it is being run on an ARM platform and uses the ARM64 Version instead of the usual and working x64 Version.
The solution was to copy a working Visual C++ x64 installer from a x86-64 machine and use that installer, or just directly copying the dlls (11 in total) from a x86-64 machines C:\Windows\System32 folder to the same folder on the ARM machine)
the following dlls are needed (do this at your own risk, might cause problems with other apps)
concrt140.dll
msvcp140.dll
msvcp140_1.dll
msvcp140_2.dll
msvcp140_atomic_wait.dll
msvcp140_codecvt_ids.dll
vcamp140.dll
vccorlib140.dll
vcomp140.dll
vcruntime140.dll
vcruntime140_1.dll
Now Allplan is able to successfully start and as far as I can tell from a short test, it runs without crashing, although relatively slow when opening functions, even with 8 cores and 40GB of memory of an M1 Max.
