Android Question trying to publish my app googleplay

[mbatgr]

1. I sign the app wihin B4A and got myprivatekey.keystore

2. Download perk

java -jar pepk.jar --keystore=C:\_B4X_folders\B4A\Projects\myprivatekey.keystore --alias=b4a --output=C:\_B4X_folders\B4A\Projects --encryptionkey=eb1.....e6aa

I use the same password when created the b4a private key for myprivatekey.keystore and the alias (b4a)
But got error

Error: Unable to export or encrypt the private key
java.nio.file.AccessDeniedException: C:\_B4X_folders\B4A\Projects

PS C:\_b4x_folders\b4a\projects>

Any suggestions to unstack?

Why are you ignoring my answer: https://www.b4x.com/android/forum/threads/googleplay-tutorial-for-uploading-apk.119033/ ?
Why make things more complicated than they should be?

No I try to follow the instructions but stuck on 1. when it asks me the password for my keystore and the alias password...

Why are you using Google Play signing? You don't need to.
