FAQ

Click the "Buy Now" button in the 【Pricing】 section. You will be redirected to our secure payment partner, Lemon Squeezy. We support major Credit Cards, PayPal, Alipay, and WeChat Pay globally.
It's automatic! After successful payment, a License Key will be instantly sent to your email address. Open H2E Studio, go to "License Center", enter your Key to activate immediately. No manual contact required.
We understand your concerns. Since software licensing is a virtual digital product:
  • Before activation: If you haven't used the Key, you might be eligible for a refund depending on the payment platform's policy.
  • After activation: Once the Key is used and bound to your machine, we cannot offer refunds. Please try the free version fully before purchasing.
Core features (1.5GB support, Krpano, WebView2) are identical.
Difference: Free version EXE has Splash Screen Ads and Watermark, and does not support "Commercial Licensing System" or "Online Update". It is suitable for testing. For delivery, please purchase a license.
No longer supported.
To ensure best security and support for modern Web standards (WebGL 2.0, ES6+), H2E Studio uses the latest WebView2 runtime.
Since Microsoft stopped supporting Win7, we decided to only support Windows 10 and above.
H2E Studio core is digitally signed, minimizing false positives. However, heuristics of some AVs might trigger warnings. We recommend submitting your software to AV vendors for whitelisting.
None.
The EXE generated by the paid version is completely clean, with all ads/watermarks removed, and all attribute modifications (Copyright, Company Name, etc.) unlocked.
Yes.
Vue, React, Angular, and all modern frameworks are supported. It uses a modern browser kernel, ensuring CSS3/JS works exactly like in Chrome. "What you see is what you get".
Yes.
It defaults to 32-bit (best compatibility). For 64-bit, just check "Win 64 Architecture" in the 【Advanced Options】 tab.
Yes.
The tool has a built-in engine that automatically converts dragged .png/.jpg/.bmp images into standard .ico files.
There is also an independent converter under Menu 【Tools】 -> 【Image to ICO】.
Before WebView2, tools (like Electron) had to bundle the entire Chrome browser, causing bloat.
H2E Studio uses Microsoft's WebView2, the perfect modern upgrade:
  • IE Kernel: Obsolete. Insecure and incompatible with modern web.
  • Bundled Chrome (Old way): Size over 100MB, hard to update securely.
  • WebView2 (Our way): Microsoft Recommended. It calls the system's Edge (Chromium) runtime. It is essentially Chrome, but shares system resources, achieving 3MB Size and Bank-level Security.

Compliance & Disclaimer

1. Illegal Use Prohibited

H2E Studio is for legal software development only. It is strictly prohibited to pack any content involving gambling, pornography, fraud, phishing, malware, terrorism, or any content violating laws.
