This isn't working for me in the 32-bit version of Sonar 8.5.3 either, although the 64-bit version works. The 32-bit installer says that it is the wrong version. I think maybe if you already installed the Buddy meters
prior to upgrading to 8.5.3, the installer will continue working because it is really looking at the patched 8.5.2 file, not the one that comes with the 8.5.3 patch. That is just a guess though.
The error I get is:
"TTSRES85.dll" is not the right file to patch ! (or wrong version) (while reading TTSRES85.dll...)
