In order to use MOPS CLI or certain versions of the InstantUV SDK, you will need a keyfile. In order to make the software find it, there are two options:
- Place the keyfile, which must in this case be named iuv_keyfile.xml, inside your current working directory.
- Place the keyfile in an arbitrary location and make an environment variable IUV_KEYFILE point to it (not to its directory).
For example, if you placed the keyfile in C:/keys/, then the value of IUV_KEYFILE should be C:/keys/iuv_keyfile.xml.
The second option is the preferred one, as it is way more flexible.
