@rem --------------------------- Intro -------------------------------
echo This script will install InvokeAI and its dependencies. Before you start,
echo please make sure to do the following:
echo 1. Install python 3.9 or higher.
echo 2. Double-click on the file WinLongPathsEnabled.reg in order to
echo    enable long path support on your system.
echo 3. Some users have found they need to install the Visual C++ core
echo    libraries or else they experience DLL loading problems at the end of the install.
echo    Visual C++ is very likely already installed on your system, but if you get DLL
echo    issues, please download and install the libraries by going to:
echo    https://learn.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist?view=msvc-170
echo.
echo See %INSTRUCTIONS% for more details.

@rem ------------------------ Subroutines ---------------
@rem routine to do comparison of semantic version numbers
@rem found at https://stackoverflow.com/questions/15807762/compare-version-numbers-in-batch-file
:compareVersions
::
:: Compares two version numbers and returns the result in the ERRORLEVEL
::
:: Returns 1 if version1 > version2
::         0 if version1 = version2
::        -1 if version1 < version2
::
:: The nodes must be delimited by . or , or -
::
:: Nodes are normally strictly numeric, without a 0 prefix. A letter suffix
:: is treated as a separate node
