I created an article named "SVN with PowerBuilder - Single User.pdf" that describes the solution to this issue; it is available in the ARTICLES section.

Summary:  I cannot seem to be able to connect the PB Workspace SCC Properties with SVN, using Tortoise.

Details:  Here are the steps I have taken.
Windows 7, 32-bit o/s
PBv12.1, build 7055

I followed the instructions on this page to integrate SVN with my PowerBuilder code:
    https://power2build.wordpress.com/2014/08/15/powerbuilder-and-svn-2/

1.    I have installed SlikSVN.
The code resides in “C:\Program Files\SlikSvn”
SlikSVB shows up in the Control Panel in the “Programs and Features” window.
The svn.exe file resides in “C:\Program Files\SlikSvn\bin”.
The last entry in the PATH variable is “C:\Program Files\SlikSvn\bin”.

2.    I have installed TortoiseSVN v1.9.7.27907 (32 bit).
The code resides in “C:\Program Files\TortoiseSVN”
TortoiseSVN  shows up in the Control Panel in the “Programs and Features” window.
The TortoiseProc.exe resides in "C:\Program Files\TortoiseSVN\Bin"
The entry in the Start Menu is:
    "C:\Program Files\TortoiseSVN\Bin\TortoiseProc.exe" /command:rtfm

3.    I have installed the PBSCC proxy
The code resides in "C:\Program Files\TortoiseSVN\”
PBSCC  shows up in the Control Panel in the “Programs and Features” window.
PbSccDel.exe resides in “C:\Program Files\TortoiseSVN”.
Pbscc.dll and pbscc_expat.dll – reside in “C:\Program Files\TortoiseSVN\bin”.

The three installations for SVN source control with PowerBuilder

4.    The code to be put under source control is under the “C:\APPS12\build12\compile” directory:

5.    Using Tortoise, I created a repository in “M:\Dev PB12\Source Control\Subversion\ICABS4_4_Repository”

6.    Next, I opened the Tortoise RepoBrowser and created my two  projects:

7.    Then I attempt to set up the PB IDE Workplace properties for Source Control.

In the PROJECT field, I navigate to my new project folder on the M drive:
    M:\Dev PB12\Source Control\Subversion\ICABS4_4_Repository    

And I immediately get the following error:

SVN.exe exists on my computer
The PATH is correct.

I try the cmd line test specified in the error msg.

And I get:

8.    Based on the error message above, I create a WORKING repository:

a)    When I add the folders, Tortoise automatically adds the PBLs:

Here is the folder of the new working repository

9.    I go back to the PB Workspace properties and try again to establish SCC connections, pointing the PROJECT to the SVN_WORK_REPOSITORY: 
“C:\APPS12\SVN_Work_Repository”.

When I select that folder I get the same  error:

At this point I've no idea how to proceed.

HELP!!!
 

Thank You,
