I have the same problem as you and Dean suggested me to do something. Then, it works. Below is the link you can download and try it.
http://thaiastro.nectec.or.th/pop/Do...Microtouch.rar <-- 5,646 KB.
After you download, then extract them. There are 2 folders.
Before install, make sure you have a privileged as administrator.
First step.
run setup.exe in folder "01_win7_MicroTouch_driver"
Then, go to your FocusMax and find your Featouch focuser. If there is exist. There is no need to do step two. If there is not FT in the list. go to step 2.
step 2.
Please read instruction in file "MicroTouch ASCOM Fix.txt" which contained in the folder "02_MicrotouchASCOM-Fix"
I copied the instruction to show below.
================
Extract the MicroTouch.Focuser folder from the ZIP file.
Go to the following directory:
c:\Documents and Settings\All Users\Application Data\ASCOM\Profile\Focuser Drivers
Copy the MicroTouch.Focuser folder to this directory
Note that "Application Data" is a hidden folder. To turn on hidden folders, go to Tools > Folder Options at the top of the window. Go to the View tab. Check "Show Hidden Files and Folders".
================
Hope this help.
