This is what I did to get it installed.

1. downloaded and unzipped to C:/visualvm_launcher_u1_eclipse_36/

2. Eclipse Window --->Preferences ---> Available Software Sites --> Add (Name: VisualVM; Location: file:/C:/visualvm_launcher_u1_eclipse_36/)

3. Eclipse Help ---> Install New Software ---> Select VisualVM from drop-down menu ---> Expand Uncategorized ---> Select VisualVM Launcher Feature ---> Next

It looks like you are not following the steps for installation. You should:

1. unzip visualvm_launcher_u1_eclipse_36.zip into directory of your choice
2. add local update site pointing to the chosen directory
3. install VisualVM Launcher Feature

The file itself may be corrupt that you are trying to add as an archive. Examine the root level of the file and make sure the correct components are there. Right now, I am trying to install EPIC in such a way. What I see in the zip file at the root level are:

• features (folder)
• plugins (folder)
• README.txt (file)
• site.xml (file)
