Multiple issue while installing DX-Spectrum as User Account Control (UAC) was not disabled
If you plan to install CA Spectrum as a user other than Administrator, turn off User Account Control (UAC).
Spectrum installation software requires administrator privileges to evaluate available resources and to run custom installation scripts. An initial installation generates residual files with administrator ownership. Subsequent upgrade installations also require administrator privileges.
