TurboTax 2018 WinPerReleaseEngine then Reinstall error

I returned to TurboTax 2018 Premier on Windows for the first time since April 2019 to make an estimated tax payment. When I double-clicked its icon, TurboTax displayed an alert

TurboTax 2018 WinPerReleaseEngine
Please wait while Windows configures TurboTax 2018 WinPerReleaseEngine

 

but after several seconds displayed the error

 

BUG: TurboTax won't let me select and copy the text of the error message, this is me hand-typing:

 

The file ‘_lmth.0003001_tnetnoCpleH_gnimroftalpeR_tib23_rgnerepw_ cannot be installed because the file cannot be found in Cabinet file ‘TurboTax.cab’. This could indicate a network error, an error reading from the CD-ROM, or a problem with this package.

and then "Fatal error during installlation."

 

I don't know where WinPerReleaseEngine or TurboTax.cab live, they aren't in C:\Program Files (x86)\TurboTax\Premier 2018\ .

 

I found an Installer in that directory and am attempting Repair, and that popped up its own failure alert

BUG: I can't ^%$#@! select the text in this error either! Get a clue, Intuit!

BUG: I apologize for the poor formatting, but when I try to indent the error messages, this forum post editor complains about invalid HTML in the message body. Sigh.
