Thanks to Julia CJ my issue is resolved. Her steps below fixed the problem:
"Open Registry Editor and find the such sequence:
1) HKEY_LOCAL_MACHINE/ Software/Wow6432Node/Candleworks/FXTS2/InstallPath
Note system type (32 or 64)
If you haven’t saw such file (InstallPath), you need to create it:
By the right mouse button choose the command “Create”/ Expandable String Parameter.
The file name should be “InstallPath”.
Please see the attached snapshot at your mail:
stazitoforex@gmail.com.
2) Clicking by the right mouse button you specify this way:
C:\Program Files (x86)\Candleworks\FXTS2
And after it open FX Strategy Wizard. It should work correctly."
Note: I needed to create new Registry keys as they did not exist at first. Same process just two added steps for adding Candleworks and FXTS2 keys (right click > add > key) so that I could use InstallPath in the correct location.
Thank you!
