ExecWait 'MsiExec /x "$uninst-key" /qn'

Can't seem to get ExecWait MsiExec to work with a variable.

the following works all day ..
ExecWait 'MsiExec /x{64A3A4F4-B792-11D6-A78A-00B0D0170970} /qn'

the following cmd -

ExecWait 'MsiExec /x"$uninst-key" /qn'

generates the following log output ....

Any help would be greatly appreciated.

Try removing the double quotes around $uninst-key? (provided it doesn't have spaces).

tried that too, didn't work. the docs suggested using the quotes around the variable.

https://blogs.msdn.microsoft.com/cja...windows-vista/ says that 1605 is ERROR_UNKNOWN_PRODUCT.

Use Process Monitor and compare the working and non-working scenarios...
