This tutorial is based on BlueStacks 2.
If you are getting this issue it might be due to less free space available in the C: drive (or where Windows is installed).
The free space available should be approximately 4 GB more than the sum of data present on the Internal Storage and SD Card on BlueStacks. You can calculate the data present from the Storage under the setting on BlueStacks.
If you continue getting this issue, please raise a ticket on ZenDesk and our support team will take care of your issue.
