Failed to import package with error: Couldn't decompress package

[xushuo1236]

Hello guys,

I have purchased a package from the Unity asset store.
After I complete downloading, an error occurred as I imported it (showed as following).

The directory is fully in English and there is enough disk space on my computer. Anyone know what should I do to import that file and fix the problem? My current Unity version is 2019.1.4f1. I am downloading a lower version of Unity to try.

If anyone knows what to do, I need your help!

Sincerely appreciate,
Best,
Shawn

I have tried the 2018.4.5f1 version of Unity just now but still cannot import the file. Same problem as above occurred.
Need Help!

I had same error because Unity download assets on C:\Users<username>\AppData\Roaming\Unity\Asset Store-5.x. My C: drive was full when downloading it. On next start unity believe that the related package was successully downloaed so package install on the project fails after.
Solution :

• delete corrupted asset under C:\Users<username>\AppData\Roaming\Unity\Asset Store-5.x
• make enough space on your C: drive
• go to asset store and reload the asset
• install the asset in your project

Everything is very simple. You don’t have enough hard disk space
