Node, thank you for your input. It's not that I don't respect people's time, it's that I have never tried this before and don't really know what information would be helpful. I really do appreciate you trying to help me get this solved.

Started from fresh Windows 11 Pro install on brand new ThinkPad T14S with 2TB hard drive. Purchased ISTA+ package from bimmerdiagnostics.com and downloaded. Unzipped install package to desktop with 7zip. Installed .NET framework. Installed BMW Standard Tools using included standard tools installer. Installed ISTA 4.32.1.using their included standalone installer. The PSdZ folder is missing from the package they provided so following installation I located what seems to be the most current data (v4.43.10_PSdZData) which I then copied into the ISTA/PSdZ folder. Diagnostics worked perfectly but no programming. Tested on 3 different vehicles: F10, F25 and E70. Same result on each vehicle with the Programming tab greyed out (I know programming won't work on E70 with ISTA+ and that I need ISTA-P for this chassis). Deleted all program files, restored windows to previous restore point then tried this entire process again with the same results.

*I am now wondering if I should have put the PSdZ folder into the main installation package before running the standalone installer. If that is the case it threw me off because folder name didn't match their example (SDP 4.xx.xx).

Currently, I have just downloaded Sedoy's last standalone (4.39.20) and noticed that it includes 4.39.20 PSdZ data in the root folder. I'm thinking I might try to install his version next. My question for this installation is if I replace the 4.39.20 PSdZ data with the 4.43.10 data I have if it will load that new data and function? I am going to try this and will report back. Hopefully 3rd time is a charm. (If that doesn't work I am currently downloading an Offline ISTA version from shawnsheridan).
