Not a problem! Glad it helped.

If you want me to test the fix on one of my VMs, I can. Just tell me what specifics you want me to verify (other than the error going away during install, obviously).

@KryziK: thanks for pinpointing the specific part of code - that sped things up.

Fix has been committed to git repo. I'll release 1.46 in a day or two after fixing one more problem with shell extension. If anyone would like to test the fix - please pm me.

Sorry for double-post.

Code Select Expand

void TRegistry::ReOpen(HKEY key, const wchar_t* pszKey, bool bReadOnly /*= true*/)
{
if (!pszKey)
throw std::invalid_argument("pszKey");

if (m_hKey)
RegCloseKey(m_hKey);

LSTATUS lStatus = RegOpenKeyEx(key, pszKey, 0, bReadOnly ? KEY_QUERY_VALUE : KEY_ALL_ACCESS, &m_hKey);
if (lStatus != ERROR_SUCCESS || m_hKey == nullptr)
throw std::runtime_error("Cannot open registry key");
}

Can confirm that throw std::runtime_error("Cannot open registry key"); is getting hit.

What is the exact version of Win10 that you've used?
Looks like some dependency problem, but I'll have to try reproducing it on some clean Win10 vm.

OS Name   Microsoft Windows 10 Pro
Version   10.0.19041 Build 19041

Can confirm there's an issue on Win10-x64 with running regsvr32 on the chext dll.

Attempted with the following:
* Running as admin
* Any/all antivirus disabled

However, when I first installed v1.44, and then immediately after installed v1.45, it appears to have worked. There might be a bug in anything it's expecting to already exist when v1.45 is the FIRST version the user has ever installed. It could possibly be DllRegistration.RemoveLegacyEntries crashing if those entries don't exist?

this happens woth copy handler 1.45 (chext64.dll is the origin of failure) tried 1.44: no problem

Try installing v1.45 now, without uninstalling v1.44. Does it work?
