My error is exactly the same as has been previously reported in this issue https://e2e.ti.com/support/tools/simulation-hardware-system-design-tools-group/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1090279/pspice-for-ti-installation-interface-disappeared?tisearch=e2e-sitesearch&keymatch=PSPICE-FOR-TI%2520install#
I had a look at the following location "C:\Users\{USER}\AppData\Roaming\Cadence\PSpiceTIInstall\" for the log file "cdsPspiceTIlog.txt" but no such file exists. The only files in the directory are helpt.html, pcbsystemreqs.html, TISpice.exe & TIPSpice.exe.config.
