The error you have as well as the content of the file wampmanager.ini shows that the installation was not carried out correctly, the installation VARIABLES were not replaced by their true values, for example, WAMPROOT should have been replaced by the actual installation path, for example c:/wamp64
It seems that you did not launch the installer as an administrator.

- 1 - Uninstall Wampserver.

- 2 - Verify that all VC ++ packages are installed and with the latest versions.
To do this, use the tool:
Checks VC++ packages installed
Do not use a previously loaded tool. Make a new download to make sure you are using the correct version.
To download missing packages, do not rely on Microsoft links, they are not reliable, download packages on in section Visual C++ Redistribuable Packages
Do not forget that if you have a 64 bit Windows, you must install both 32 and 64 bit versions of each package.
You must install each package "as an administrator", so right-click the exe file and then run as Administrator.

- 3 - Install Wampserver 3.1.9 as an administrator.
