I.e.29.01.12 Fixed: Updated unrar64.dll to latest version. Can't update 32-bit unrar.dll because it no longer supports Windows 9x/ME/2000 (64)
+ T.C. 8.0ß18 64-bit brings along Unrar64.dll v4.10.100.374.
+ T.C. 8.0ß18 32-bit brings along Unrar.dll v4.04.3.
We users of the more recent 32-bit Windows versions like Vista Home Premium 32-bit SP2 or Windows 7 Enterprise Edition 32-bit SP1, may we assume that it will be technically all right to replace the unrar.dll which T.C. 8.0ß18 32-bit brings along by the original 32-bit Unrar.dll v4.10.100.374 which we have downloaded from the genuine RarLab download page here: unrar.dll ?
By the way, isn't the minimum required Windows version Windows 2000? So Windows 2000 is supported?
Kind regards,
Karl
