I am installing to Delphi 10.2 but the BPL's that are supposed to be in C:\Users\Public\Documents\Embarcadero\Studio\19.0\Bpl are not there. The 64 bit ones are in the Win64 folder.

In 10.3.2 the installer runs correctly.

Hello Andre

I did an installation on one of our test machines and there the bpl files were generated as expected.
Would it be possible to mail the installation log file to us?
You can find this in your window documents folder with a name similar to TMS VCL UI Pack_10.x.x.x.log.

I had a look through it. The installer didn't say anything about failing, the log did. We use a subst drive to store projects on and it was attempting to compile (only) the 32 bit version bpls to this drive instead of the c: drive. I removed the subst drive and now the install works as expected.
There must be a reg key somewhere that the installer decides to use?

What exact error message was in the log file?

I'd suggest to contact us by email and attach this log file so we can see what exactly happened on your machine.
