If Juniper pulse secure will not install on your computer in my case windows 10, chances are you are running into a driver issue.
Here is how to solve it:
First Step
Open CMD as an administrator and run the following:
pnputil -e > pnplist.txt this command enumerates the driver packages that are currently in the driver store
Second Step
then open the txt file and locate anything that says Juniter in the “Publisher name” and run the following command:
pnputil -d "Publisher name" in my case pnputil -d oem8.inf
Third Step
Reinstall Juniper pulse secure
