--- Comment #5 from Damjan Jovanovic damjan.jov@gmail.com --- Basically if the absolute path length to readme.txt (Z:\path\to\wineprefix\then\path\to\readme.txt) is 260 (MAX_PATH) characters or more, dotnet20 fails somewhere and causes this problem.
Exactly the same happens on Windows: a long base path giving an absolute path length of 256 characters works, but an absolute path length of 267 characters gives the same error.
'Z:\home\sam\src\wix-test\depth\A\AOL\Aachen\Aaliyah\Aaron\Abbas\Abbasid\Abbott\Abby\Abdul\Abe\Abel\Abelard\Abelson\Aberdeen\Abernathy\Abidjan\Abigail\Abilene\Abner\Abraham\Abram\Abrams\Absalom\Abuja\Abyssinia\readme.txt' is only 219 characters long, so assuming that was the real path used (and not something the OP trimmed it to), maybe there was another path length problem when this bug was reported, that has been fixed since. If so this should be RESOLVED FIXED. If not, it should be RESOLVED INVALID.
Given confirmation by 2 other users in 2014 and 2015, I'll assume that paths < 260 characters long (eg. 219 in the OP's case) were a problem back then, and no longer are. So resolving FIXED. Thank you for your bug report :).
