After installing SRAdmin the Install Spectrum option is grayed out.
The base version of Spectrum must be installed first. Service Pack and HotFix installs require the base version of Spectrum to be installed first.
If attempting a Service Pack or HotFix installation the base version of Spectrum must be installed first.
For instance, if installing Spectrum 10.2.3, the base version Spectrum 10.2 must be installed before 10.2.3 can be applied. Service Packs and HotFixes are not full versions
of the product. They only contain the files necessary to install themselves. So, 10.2 in this example must be installed first.
