Unhappy [Q] New to Viper Rom - App install failure

Hi All,

It's been awhile since I rooted a phone and decided to do this on my now old HTC EVO 4G LTE (Sprint) phone last night. I installed Viper4G ROM 3.1.7 with stock Kernel.

hardware version: 3
Android: 4.1.1
HTC Sense: 4+
Software: Viper4G 3.1.7

Everything is working great and the ROM is beyond what I've experience in the past.

The only issue I'm having is that some of my apps will not install with the following error "Couldn't install on USB Storage or SD Card".

Some of the Apps that failed are:
- Soundhound Pro (Yes this purchase version)
- PowerAmp Pro License
- X Scope Broswer

And few more. Is there something I need to change during the installation process for these apps or am I doing something wrong?

Thanks in advance,
T
