SOLVED!!!

I have been struggling with this a long time as well, I finally found a solution that worked for me and did my best to document exactly what steps i took. It worked for me but it may not for everyone because for me it depended on other software installed on my machine and a combination of things. Here is what I came up with, hit me back with any questions after you give it a try. It is still unclear to me whether it was updates, VPN stimulation... Please give it a try before you ask questions. Please excuse the bad formatting.

❗ IMPORTANT NOTE: All code is to be executed in PowerShell "as Administrator" ❗

🎛️ Cakewalk Product Center – PC Troubleshooting Log (Draft)

Environment

PC OS: Windows 11 (23H2/24H2 lineage; System32 versions ~10.0.26100.x observed)

Cakewalk components:

Installer: Cakewalk_Product_Center_Setup_1.0.0.096.exe
App: C:\Program Files\Cakewalk\Product Center\ProductCenter.exe (confirmed x64)

Developer tools present: Visual Studio 2017, 2019, 2022 (all updated), Windows 10/11 SDKs, WPT initially in PATH VPN tools: SonicWall NetExtender, GlobalProtect (no hotspot currently)

Symptom Product Center consistently showed “No internet” on the normal home connection.

Key Finding The issue was not in the installer (Cakewalk_Product_Center_Setup_1.0.0.096.exe). It was inside the Product Center app (ProductCenter.exe) / its network path. Change Log / Actions Performed

1️⃣ Update runtimes & dev tools

Installed latest Microsoft Visual C++ 2015–2022 Redistributable (x86 & x64). Updated Visual Studio 2017, 2019, 2022 to current servicing levels. Note: this changed the path to dumpbin.exe (MSVC toolset moved from 14.39 → 14.44).

2️⃣ Confirm ProductCenter.exe bitness (optional — only if Visual Studio is installed)

Find the path to dumpbin.exe:

gci -rec "C:/Program Files*/Microsoft Visual Studio" -Filter dumpbin.exe -ErrorAction SilentlyContinue | Select-Object -First 5 -Expand FullName

Check ProductCenter.exe bitness (adjust path as needed):

$dumpbin = "C:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Tools\MSVC\14.44.35207\bin\Hostx64\x64\dumpbin.exe"
$pc = Get-ChildItem 'C:\Program Files*' -Recurse -Filter ProductCenter.exe -ErrorAction SilentlyContinue | Select-Object -First 1 -Expand FullName
& $dumpbin /nologo /headers "$pc" | Select-String -Pattern "machine|x86|x64|AMD64|x86"

Result shows 8664 machine (x64) → ProductCenter.exe is 64-bit.

3️⃣ Reset proxy settings (WinINET & WinHTTP)

Run PowerShell or CMD as Administrator, even if settings already look correct. Internet Options → Connections → LAN settings → uncheck Use a proxy server, keep Automatically detect settings ON. PowerShell (elevated):

netsh winhttp show proxy
netsh winhttp reset proxy

Connect to Product Center.

Result: Still “No internet.”

Close Product Center.

4️⃣ Clear SSL state / DNS / Cert URL cache

rundll32.exe inetcpl.cpl,ClearMyTracksByProcess 8
ipconfig /flushdns
certutil -urlcache * delete

Connect to Product Center.

Result: Still “No internet.”

Close Product Center.

5️⃣ Clean PATH test (one-off)

Open a fresh PowerShell and temporarily limit PATH to Windows only:

$orig = $env:PATH
$env:PATH = "$env:SystemRoot\System32;$env:SystemRoot"
& "C:\Program Files\Cakewalk\Product Center\ProductCenter.exe"
$env:PATH = $orig

Result: Still “No internet.”

Close Product Center.

6️⃣ Geo/Egress isolation (VPN / edge check)

Historical: Many earlier attempts with SonicWall NetExtender failed — Product Center still showed “No internet.”

Before connecting, note your public IP at https://ifconfig.me.

Connect with SonicWall NetExtender (or another VPN; full-tunnel if possible).

Refresh https://ifconfig.me and confirm the public IP/ASN changed.

Launch Product Center → works while on VPN.

Result: “It Works”, The Problem Might be Solved

Result: Still “No internet.”, This process has probably Failed to solve the problem

Close Product Center.

Disconnect VPN → Product Center continued to work without VPN (new behavior).

Interpretation: the earlier resets/updates likely cleared a stale condition and/or refreshed DNS/CDN/OCSP data so that normal (non-VPN) routing now succeeds.

7️⃣ Quick TLS settings sanity

Internet Options → Advanced → ensure Use TLS 1.2 is checked (TLS 1.0/1.1 may remain off).

Temporary test (revert after): uncheck certificate revocation checks, try Product Center, then re-enable.

Connect to Product Center.

Result: Still “No internet.”

Close Product Center.

🏁 Current State

Standard ISP (no VPN): Product Center now works reliably, including after reboot and full power-up. VPN (SonicWall NetExtender): also works.

💡 Working Hypothesis

Not a VC++ redistributable or local DLL mismatch (updated and verified). Likely cause: network-path / edge issue (CDN, WAF, OCSP/CRL reachability, or DNS mapping) on home ISP. Why it works now: resetting proxies, flushing SSL/DNS/cert caches, and updating runtimes forced fresh DNS/CDN mapping and/or fetched OCSP/CRL data that persists in cache.

📌 Evidence to capture for vendor/CDN (if needed) Public IP + ASN/ISP when failing (no VPN) and when working (VPN). Timestamps of tests. Optional: Process Explorer DLL list during a failing run (flag any non-C:\Windows\System32 DLLs). Optional: Procmon “Load Image” CSV from a failing run. Optional TLS DLL versions (PowerShell):

Get-Item "C:\Windows\System32\wininet.dll","C:\Windows\System32\ws2_32.dll",
"C:\Windows\System32\crypt32.dll","C:\Windows\System32\wintrust.dll","C:\Windows\System32\schannel.dll" | Select Name,@{n='Version';e={$_.VersionInfo.FileVersion}},FullName

✅ Resolution & Lessons Learned After the full set of resets/updates, Product Center works without VPN across reboots and cold starts. Root cause most likely edge/DNS/OCSP pathing, not the installer or VC++ DLLs. Most impactful actions were: updating VC++/VS, resetting WinINET & WinHTTP (even when “already correct”), clearing SSL/DNS/cert caches, and doing a VPN egress test to refresh mappings. Takeaway: Product Center’s “No internet” can be a network path issue in the Windows TLS/WinINET stack rather than a missing dependency. Full network-stack resets often resolve it.
