Error -603 occurred at Read Registry Value

Asked By 40 points N/A Posted on -


My computer has Windows 7 x64. I am using 32-bit LabVIEW with right clicking and choosing Run as administrator. However while I attempt to examine a value I have located in HKEY_LOCAL_MACHINE/SOFTWARE, it sends me an error 603 stating the value does not exist.

I can view the value in the registry editor, and I can study values from further HKEY_LOCAL_MACHINE sub keys, like as HARDWARE OR SECURITY. Whenever I put in writing to HKEY_LOCAL_MACHINE/SOFTWARE, I am not able to see it reproduced in the registry editor, on the other hand I don’t receive an omission message.

LabVIEW: Specified key or value does not exist.

Error -603 occurred at Read Registry Value


This error might be caused by a corrupt registry entry, an older version of the registration VI, or a corrupt CCDB file. National Instruments saves most of its VI Server configuration information in a file called nati.ccdb, which is located in the Program FilesNational Instruments folder. This ccdb file might become corrupt. Complete the following steps to resolve this error:

  1. Close all running programs.
  2. Move the nati.ccdb file to another folder, or rename (etc. nati.ccdb_old).
  3. Start LabVIEW to recreate the CCDB file.

If this doesn't resolve the 603 error, you can mass compile the LVDSC directory.
