0.85: Wrong "bitness" of BPGDEC.exe on 32bit version

In 32bit version, BPGDEC.exe and dependencies are 64bit. Same with latest version of XnConvert.

Ouch, that is serious. I guess Pierre will provide a new 0.85 32bit very soon.

@Pierre: I'm not very familiar with "bitness". Is this a serious problem or not so serious? What are the consequences of the wrong bitness?

Normally 32-bit software can only interface with 32-bit software, and 64-bit software can only interface with 64-bit applications.

A common example is that 64-bit XnView software versions require 64-bit Ghostscript, and 32-bit versions require 32-bit Ghostscript, but as far as I know the same is true for plug-ins and other software in general, so that many file formats that require plug-ins are currently only supported in 32-bit XnView software, as 64-bit versions of the plug-in required are not available.

Another example was access to TWAIN scanning from XnView MP 64-bit, which wasn't available until recently as the 64-bit utilities the interface required weren't normally available: the solution was ultimately for Pierre to create special 'bridge' software so that the 32-bit versions could be used.

"Bitness" was a new term to me, although self-explanatory, but Googling it, it evidently does exist: bitness and has been used by Microsoft.

If anything I've written is incorrect, please correct me... :wink:

The 0.85 software package was updated. It should be correct, now.

Good to read that this was fixed.

@cday: Thank you for your explanation on "bitness". This helps to understand things better. :)
