Class not Registered(Exception From HRESULT:0x80040154

Karthi Keyan

hi.

i am developing s/w in c#, using vs2010,and mssql. i was connecting the finger print device with my s/w. for that i convert the ocx file to dll in my system. then the software working fine in my system. i debug the software in x86. but the software is not working fine in my client system. when that call the fingerprint device dll it show the

"Class not Registered(Exception From HRESULT:0x80040154(REGDB_E_CLASSNOTREG))".

at the end of the error it show the line number of that dll calling function. so i tried to register the dll in my client system but i got the error

" The Module Failed to load. Make sure that the binary" is stored at the specified path or debug to check for problems with the binary or dependent dll files. the specified module could not be found"

i tried everything to register the dll. but i can't. open the cmd as administrator, using regsvr32 name.dll, copy the dll and paste it in system32, and register the dependent dll like msvcrt20, msvcrt40, mfc30,mfc40,olepro32,,,,, but nothing helpfull..

now i am clueless... if someone give the solution i really appreciate them.. thank you... advance thanks....

sir,
That is the ocx file given with the fingerprint sdk. filename is FP_CLOCK.ocx. i convert that ocx file into the .dll using Aximp.exe. that dll name is FPLOCK.dll. and you mentioned that install the setup of fingerprint sdk. what is that??? because they didn't given any setup file with the sdk.

Hi
have u tried with the second option. if yes then while making the setup just put all dll while making setup. and install that setup and then try.
By the way may i know the dll name. which you are trying to register. If it's a .net dll then need to install the .net framework ion the client machine.
and if it's the fingerprint sdk dll then install the setup of fingerprint sdk in client machine.

have you provided proper path of the dll while registring.
if it's not work then i will suggest just put the dll in root of the application and then try.
