This has been released. Thanks for testing!
I've just posted a pre-release of ClamWin Portable 0.93. This new version uses an updated version of the MS VC runtime files internally with a new manifest file, so I wanted to post it as a pre-release to ensure it's working as expected for all users including upgrades.

I haven't updated the icon or splash to the new ones yet but will for the final release.
Please test and post your feedback.
