Move ComStudy To A New Machine

Submitted by Mick on Mon, 2009-09-21 12:15.

Be advised that due to this being a lengthy (and sometimes troublesome) process, we cannot provide phone support for this process. We are, however, happy to provide followup posts to this page as needed.

First, copy all your ComStudy folders to your new machine - you will most likely have thefollowing - if you changed your installation directory, then you should already know where these folders are located:


For this process to work properly, you must copy these folders to the same location on the new machine.

On the old machine, go to START|RUN and type 'regedit' (no quotes)
Click the plus sign next to HKEY_LOCAL_MACHINE
Scroll down, click the plus sign next to SOFTWARE, then RADIOSOFT
Right-Click on ComStudy, choose EXPORT and save the file on your desktop.
You will want to move this file to the desktop of your new machine, double
click on it to import into your registry.

You will need a new key when you run the program on the new machine for the first time.

64-bit Operating Systems are a little trickier than the above steps. If you are going FROM a 32-bit OS to a 64-bit, you will need to edit the .reg file that you created above.

Instead of:
you will need to have

Using Find/Replace in a text editor will make changing the path easier on you.

If you are moving from one 64-bit machine to another, you will need to export HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\RadioSoft
No editing of the .reg file is needed unless you change the folder locations on the new machines.

If you run into any issues, feel free to post!

What additional issues will running Comstudy on a 64 bit Windows 7 computer cause?

Win 7 RTM runs ComStudy without issue. The Beta and RC both had a Win32 Error upon closing but only on certain systems. This was a minor annoyance and did not impact the program in any way.

Running ComStudy on 7 is almost identical to Vista in that you either need to disable UAC or run ComStudy as Administrator. This is due to (1) the installation directory you choose, and (2) read/write abilities to HKLM in the registry.

My laptop was XP which is 32 bit and the windows 7 on the new laptop is 64 bit.

I followed your procedure and have the regedit file on the new pc and the registration screen comes up.

When I click next I get an error #160 and a call Radiosoft message which shuts down the install.

Please advise re: the regedit file contents pasted in here. My file format is a bit different than yours so not sure where exactly the problem may be? Also, does each type the line HKEY... appears need to be edited? Perhaps that is my problem?

Hey, Clarence.

Yes, on a 32- to 64-bit move, you will need to either manually replace, or perform a find/replace on all instances of:


You will need to have

Let me know how it goes.
