I just had this trouble with instagram. I tried it like 10 times. I turned off Wi-Fi and it installed on the 2nd try.

Google Store is having an world wide issue; the last update they had is causing this issue. They are trying to have it fixed soon.

These days there's an issue on the Google server (with the latest Google play app update). Therefore you will receive a random package file invalid issue.

You can fix it by using a free VPS service app, apart from that in my situation, after I purchase my SGS4, I face this issue. Then I done a factory reset, after that this issue gone.

Google also know this issue and they mention they will fix it ASAP, but there's no any ETA (https://support.google.com/googleplay/an...875?hl=en)
