Since adding 64bit platform to Delphi 10.3.3 via Manage Platforms, I have not been able to install several component packs (VCL and FNC). When installing one component pack, the installer would detect a previous installation, offer to uninstall, but then uninstall a different component pack.
Now I cannot even install VCL UI Pack at all. I am getting Install Failed. The log has multiple errors the last of which is
"
Build FAILED.

Any help appreciated
