This issue can happen for two main reasons.


Issue 1: You do not have an older version of BobCAD on your computer.

This utility supports back to BobCAD-CAM V33, BobCAM for SolidWorks V9 and BobCAM for Rhino V2.


Solution 1:

If you have an older version than that, you can move your files over manually. Follow these links for further help:


If your older version is on a different computer and the older computer does not have the latest version of the software on it, download the latest version of bobcad (BobCAD Downloads), load the utility (located here: C:\Program Files\BobCAD-CAM\BobCAD-CAM V36\BcUtility.exe) and choose “Export migration file” on the older computer to export the data. Follow steps below:

1. On your old computer, download and install the latest version of BobCAD here:

2. Open a “File Explorer” on your computer and double-click on to the BcUtility.exe file located here: C:\Program Files\BobCAD-CAM\BobCAD-CAM V36\BcUtility.exe

Issue 2: You are missing the Registry Keys for your older software.

If your current computer does have the older versions of the software on your computer and the Migration tool is still not picking up the older versions, the registry keys to detect the older versions is more than likely missing.

If you open a “Registry Editor” on your computer and navigate to the Directories folder of the older version of BobCAD (Located here: Computer\HKEY_CURRENT_USER\SOFTWARE\BobCAD-CAM\BobCAD V(OLDER VERSION NUMBER)\Directories), this is where you should find a DataFolder reg key as you can see below.

If you do not see this key, that is the reason the migration tool is blank.

3. Go to File > Settings and in the General Tab, make sure there is a file path for the “Data Folder”.
