But the version according to OP is 3.6.0 which is the release from May 2020. Your link points to sth. way older. Have you mixed up things?

You're right, thanks. Version which I meant was then bumped to 3.4.0 and continues with this form of version numbering.

<p>You want to run 64bit plugins in a 32bit application - that's what the error, you got, tells us. You should install or build the 64bit version of avisynth as this should be able to work with the plugins.</p>

<p>Also Windows 7 is unsupported by Microsoft. The longer you wait with upgrading to Windows 10 (or using another modern OS) the more problems you will face.</p>

You have a path D:\Program Files\ where the 64bit version should be but do you also have D:\Program Files (x86)\ where the 32 bit version is?  Maybe sth. during installation went wrong and they both installed in the same location?

Your path `D:/Program Files/AviSynthPlus/plugins64+/` is by AviSynth recognized as an autoload path for *32-bit plugins,* because this path is set (as a value) *in an inappropriate registry key.*

Launch Registry Editor and check / change path values in these keys:

* `HKEY_CURRENT_USER\SOFTWARE\Avisynth\PluginDir+` for 64-bit version,
* `HKEY_CURRENT_USER\SOFTWARE\Wow6432Node\Avisynth\PluginDir+` for 32-bit version.

or (lower priority)

* `HKEY_LOCAL_MACHINE\SOFTWARE\Avisynth\PluginDir+` for 64-bit version,
* `HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Avisynth\PluginDir+` for 32-bit version.
