First of all: GREAT software, thanks for it. Been using it since... long time ago.

I recently moved from W7 X86 to W10 X64 and is when Im facing this problem...

Device and iCopy used to work perfectly on the W7... not working now on W10...

I've tried versions 1.7 and the one reporting... 1.6.3.32 and the no-setup version as well... with the error as a result all the times.

I get the error right after choosing the device... this is the Copy-Paste from it...

WIADiagnosis encountered an exception:
System.InvalidCastException: Specified cast is not valid.
at WIA.IDeviceInfo.Connect()
at WIADiagnosis.Module1.Main()

I tried the DLL registering but Windows won't let me replace the DLL file on the System32 path (I do have a Admin account) but instead I registered the one in the iCopy installation folder thru regsvr32 and recieved the succesfully registered message.

Thanks.
Hopefully this can get fixed and if not please just tell me.

PS: I Apologize for any spelling mistake as English is not my primary language and this doesn't seem to have a spell check :D

Dear carlos,

sorry for my late response. Do you confirm that the error is the same also for version 1.7?

Hi Carlos, I'm not an expert on this, but it struck me that in your log it's always NET-Version 2.0 instead of NET 4.0, which it's in my log. Maybe it could help to upgrade NET Framework 4 as descriped in the icopy blog: https://icopy.sourceforge.io/icopy-1-7-released/

  Hi,
  
  I guess I first had the default .NET version that comes on W10 then for backwards compatibility with some old software I still need to use I had to install .NET FW 3.5 ...
  
  I believe I have both versiones installed, please correct me if I'm wrong....
  
  Attaching current screenshots from my evidence.
  
  Thanks.-
