I found a bug how Zotero uses the pathes with holds registry keys.
Zotero 6.0.30 path is HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Zotero.
While Zotero 7.0.0 64 bit path is HKEY_LOCAL_MACHINE\SOFTWARE\Zotero.
TextMaker 64 / 32 bit works fine with Zotero 6.0.30 version.
TextMaker 64 bit works fine too.
But TextMaker 32 bit doesn't work with Zotero 7.0.0 version.
For the 32 bit applications the registry path / key doesn't exist.
WOW6432Node is a compatible folder for 32 / 64 bit applications.
