Error message that install failed: “file already exists
/data/15/2/87/123/2739612/user/3010975/htdocs/wordpress1/wp-content/plugins/wp-e-commerce/”
All the files were visible at Network solutions but at htdocs/wordpress1/wp-content/plugins/wp-e-commerce/ but nothing was visible in dashboard: plugins.
After much research deleted plugin file from NetSol file directory and installed cart66 as recommended by other frustrated wp-commerce users.
In a 100th of the time I spent researching the problem with above error message, I was instantly able to download and activate and begin using Cart66. Thanks CyFree
