Version for Windows 32-bit
A 32-bit version is usually suitable for all Windows (including 64-bit ones).
If you have a new 64-bit Windows and 32-bit software works incorrectly, try to run it in a compatible with Windows XP SP3 mode or download and install the 64-bit version of the application (if it is represented below).
Portable version for Windows
The portable version doesn't need an installation and can work from any carrier.
Besides that, the portable version doesn't leave any "trash" in the Windows system registry, so it is the most convenient and recommended for skilled users.DOWNLOAD STDU Viewer 1.6.375
