I'll bite. Here are the steps you need to take. Keep in mind that this is my best guess - I have never installed or used Cobra Show Creator, so I don't know exactly how it is supposed to work:
BEGIN:
1. Launch VMware Fusion. I assume that you are done with this.
2. Install Windows 7. I assume that you are done with this.
3. Boot Windows 7 in VMware Fusion. It sounds like you are doing this step correctly, and a Windows 7 window (with the toolbar, etc.) has appeared. What I do not understand is why the window is black. My Windows 7 window is black only while Windows 7 is booting, but I see a normal Windows 7 window once it is finished.
Fix: In the Mac VMware Fusion menu bar, select Virtual Machine->Reboot and tell us what happens. We will need more information to help you fix this issue.
Next steps:
GET WINDOWS GOING:
4. After Windows 7 is done starting up, you should see a normal Windows 7 screen with the Windows flag "Start" button in the bottom left corner. If not, log-in to Windows 7 with the account and password you created at installation. Now you should see the Windows flag "Start" button.
5. In the Mac VMware Fusion menu bar, peek at the Virtual Machine menu.
Does it include "Install VMware Tools"? If yes, select it and install VMware Tools from inside the Windows 7 window. Choose all the defaults.
If it says, "Update VMware Tools", ignore it and skip to the next step (step 6).
SET UP A SHARED FOLDER:
6. In the VMware Fusion menu bar, select Virtual Machine -> Settings (or press Command-E)
7. In the Settings window, click on "Sharing".
8. Click (checkmark) "Enable Sharing".
9. Click the plus sign, then navigate to the Mac folder that has the Cobra Show Creator installer.
10. The folder should appear in the list and "on" should be checked.
11. Close the Settings window and go back to your Windows 7 window.
INSTALL COBRA SHOW CREATOR:
12. Click the Windows flag "Start" button in the lower left corner, and select "Computer" on the right side of the menu.
13. Under Network Location, Double-click Shared Folders to open it, then Double-click your shared folder to open it.
14. Double click the Cobra Show Creator installer.
15. Follow the prompts to install Cobra Show Creator. Hopefully this is intuitive. When in doubt, accept the default.
16. After installation, you may be able to double-click a Cobra Show Creator desktop icon. If there is no desktop icon, then click the Windows flag "Start" menu and then click on Cobra Show Creator.
Additional Notes and Warnings:
* I assumed that you are using the default settings when you installed the Windows 7 virtual machine in VMware.
* I assume that those default settings are sufficient for Cobra Show Creator.
* I took you at your word that you were only going to run Cobra Show Creator. If you do much else in Windows, especially connecting to the Internet, then you must proactively make sure that it is secure by installing anti-malware software, keeping Windows updated with Microsoft monthly patch updates, etc.
Good luck! Happy Easter! Let us know what happens next.
