C3 Multi Band Compressor VST Issues

Edit: this post is rewritten.

After reinstalling Vista and upgrading Renoise, the C3 Multi Band Compressor (www.kvraudio.com/get/950.html) plugin and Computer Musics free Zebra plugin has stopped working.

I thought it was a Renoise 2.1 issue as it worked in 2.0, but I have now installed v2.0 and it isn’t working there anymore, really really weird, any ideas how come?? Thanks!

Could it be that your vista is 64bit and the plugin is 32bit?

renoise is a 32bit application so, whether your OS is 32 or 64 bit, it should still load 32 bits plugins well. what cannot be done is loading 64bits plugins onto a 32bit application or viceversa

No, that’s not why.

I think the most likely reason is the plugins are dependent on foreign DLLs, some that I had installed on the old system, but have no idea what is. :(

both plugins needed this file: msvcr71.dll in the windows/system32 folder
