These are the steps to manually make the Optima build. (Updated 11/16/2022)
Reminder before building:
    1) Make sure your local branch is updated with the latest changes from the desired remote branch.
    2) Make sure that the following files in the TIPro_Install\Optima folders includes any missing Git changes from its TIPro counterparts files: Optima.xml, Common.xml, TIPro.sln,  TIPro.csproj, Optima_64_dual.iss, and Optima_MSBuild_x86_x64.bat.  Commit your changes and apply the tag to the last commit with "Optima_5.5.XXX". 

To build Optima run the following batch file in TIPro\TI_Pro_Install\Optima folder: Optima_MSBuild_x86_x64.bat.

Please following the steps to build the Optima build manually (these instructions are valid for build 5.5.55 and higher.):
    1) Make sure TIPro branch has been checkout and switched to the desired tagged build.
    2) Visual Studio should be closed.
    3) In the TIPro\TIPro folder delete the following folders: ./bin and ./obj.
    4) Copy the following file "TIPro.sln" located in the TIPro\TI_Pro_Install\Optima folder to the TIPro\TIPro folder.  Make sure you overwrite the file.
    5) Copy the following file "TIPro.csproj" located in the TIPro\TI_Pro_Install\Optima folder to the TIPro\TIPro folder.  Make sure you overwrite the file.
    6) Open the TIPro solution file TIPro.sln in TIPro\TIPro using Visual Studio.  At most only the following files can be open during the build process: "NorthAmerica.xml" and "GlobalAssemblyInfo.cs". 
    7) Proceed to change the solution configuration to Release x86.  Now Rebuild Solution. After completion run Build Solution.  Verify that there are no errors or warnings.  If errors are present then there is a problem with Step 1 or with the build. 
    8) Proceed to change the solution configuration to Release x64.  Now Build Solution. Verify that there are no errors or warnings. If errors are present then there is a problem with Step 1 or with the build.
    9) Close Visual Studio.
    10) Proceed to create the install executable using Inno Setup 6.05 using the script file Optima_64_dual.iss found in the folder TIPro\TIPro_Install\Optima.  Use Build->Compile and verify that no errors/warnings are in the Compiler Output panel. 
    11) Rename the newly created install executable Optima_x86_x64_setup.exe to Optima_x86_x64_setup_4.2.XXX.exe found in the TIPro\TIPro_Install\Optima\Output folder.
    12) Run the install executable to verify installation and verify the application runs.  Remember to use an Optima login account to test.
    13) Once testing is complete, revert any changes to TIPro.sln and TIPro.csproj in the TIPro\TIPro folder.
