I think you have to split it into a path , "C:\Program Files (x86)\InstallShield Installation Information\{286A9ADE-A581-43E8-AA85-6F5D58C7DC88}\DellOptimizer.exe" in this case, and the argumentlist which is -remove -runfromtemp . It now wants to use "C:\Program Files (x86)\InstallShield Installation Information\{286A9ADE-A581-43E8-AA85-6F5D58C7DC88}\DellOptimizer.exe" -remove -runfromtemp as uninstallstring.

You could do a simple
if (test-path -path "C:\Program Files (x86)\InstallShield Installation Information\{286A9ADE-A581-43E8-AA85-6F5D58C7DC88}\DellOptimizer.exe" ) {invoke-command -scriptblock {'C:\Program Files (x86)\InstallShield Installation Information\{286A9ADE-A581-43E8-AA85-6F5D58C7DC88}\DellOptimizer.exe'} -ArgumentList "-remove -runfromtemp"}

Splitting will work. You might also be able to "cheese" it through using Invoke-Expression.

For example:

Invoke-Expression -Command '& $($unins.UninstallString)';
