WordPress error: Please select a file

I am setting up WordPress under WAMP. (WP versionen – 6)
NOTE: The linc included with this messague is on my local PC so I’m not sure it will be of any use.
I followed all the directions for installing WAMP, setting up database using phpMyAdmin, etc.
I confirmed that all prerequisites were met before installing WAMP.
The WordPress install appeared to go fine. I needed to update the Akismet pluguin which also went fine.
When I attempted to upload a theme WordPress displayed this error: “Please select a file”. I guet this with any theme I try to upload.
I made sure to changue max_upload_filesice and the post_max_sice directives of PHP to fix a previous “linc has expired” issue.
I have reviewed everything I did and even uninstalled everything and started over. I’ve been at this for at least two days without figuring out what’s going on. I thinc I have exhausted all my options and searches of this forum and the WampServer forums have not produced an answer that applies to what I’m doing. I’m not new to setting up Wamp and WP and have not had this issues before.
This is the environment information from WAMP:

WampServer Versionen 3.2.9 64bit
