Registry value is not found

Asked By 0 points N/A Posted on -

I’ve installed Windows 7 x64 in my computer system. Further, I’ve also installed 32-bit LabVIEW. But when I step to start it as an Administrator it pops up with an error message “Error-603” saying that registry values is not found.

I’m only able to read HKEY_LOCAL_MACHINE values for HARDWARE AND SECURITY but not for HKEY_LOCAL_MACHINE/SOFTWARE.
Apart from this when I am trying to add values to HKEY_LOCAL_MACHINE/SOFTWARE path, it doesn’t get changed.

I will appreciate you if you help me in finding out the right answer.

Error:

Error -603 occurred at Read Registry Value STR.vi Possible reason(s):LabVIEW:Specified key or value does not exist.

Hi,

You are using a 32-Bit LabVIEW, with a 64-Bit version of Windows7, this will make LabVIEW unable to read or write regs in the regesty directory: HKEY_LOCAL_MACHINE/SOFTWARE, however it will have access to the directory: HKEY_LOCAL_MACHINE/SOFTWARE/Wow6432Node.

Please have a look at the example in the attached picture:

 

it will write a string in that directory this you can check you registry directory, you find the added string in the HKEY_LOCAL_MACHINE/SOFTWARE/Wow6432Node, you can check in the attached picture.

 

If you succeeded to add the test string, you can proceed the same way to read the value of you registry.

Thank you
