How to install it, step by step
- Before installing, put your company’s Excel files in one single folder. Fold reads the Excel (.xlsx and .xlsm) and CSV files in that folder, not those in the subfolders inside it. When you install, you choose that folder, and Fold reads it without changing or deleting anything.
- You leave us your details and download the file. If your browser warns that it “isn’t commonly downloaded”, that is because Fold is new: in Edge click “…” and “Keep”; in Chrome, “Download suspicious file”; in Firefox, “Allow Download”. When you click the button we show you step by step.
- You double-click the file you just downloaded with the button above, and Windows warns you. You see “Windows protected your PC” because the installer is new and does not carry a known publisher’s signature yet. Click “More info” and then “Run anyway”. If you see “The publisher could not be verified” instead, click “Run”.
- You choose two folders. The office folder where your Excel files are (Fold only reads it: it never changes or deletes anything) and where Fold keeps its data. No administrator rights; it takes one to five minutes.
- Fold opens and you register your company inside the program. You enter your company details and your email, and confirm it from your inbox.
- You connect this computer. Fold asks “Connect this computer?” and shows a 6-digit code: click “Yes, connect”. Then a window with the same code appears; say yes and it is connected.
It is normal for your browser and Windows to warn you: it happens with any new program that does not carry a digital signature yet, and it does not mean anything is wrong with it. If you like, check the file’s fingerprint first (we explain how below).
If Edge stops the download
This is normal for a new program that is still rarely downloaded. Do this:
“Downloads” opens at the top right with the warning “isn’t commonly downloaded”. Hover over it and click the three dots “…”.
Click “Keep”.
If another window opens, click “Show more” and then “Keep anyway”. If it does not, you are done: the file is in Downloads.
If Chrome stops the download
This is normal for a new program that is still rarely downloaded. Do this:
Press the Ctrl and J keys together. “Download history” opens with the file crossed out.
Next to Instalar-Fold, click the three dots “⋮”.
Click “Download suspicious file”. The file is in Downloads.
If Firefox stops the download
This is normal for a new program that is still rarely downloaded. Do this:
The downloads panel opens at the top right with “This file is not commonly downloaded”. Right-click the file.
Choose “Allow Download”. The file is in Downloads.
If your browser stops the download
This is normal for a new program that is still rarely downloaded. Do this:
Open its downloads list: in almost all of them, press Ctrl and J together.
Next to Instalar-Fold, choose the option to keep or allow the file.
Then, when you open the file
Open the file from Downloads. If you see “Windows protected your PC”, click “More info”.
Click “Run anyway”. The installation starts.
Using another browser?
If your antivirus blocks it
Because Fold is new and its installer is not signed yet, some antivirus programs may flag it by mistake (a false positive). You do not need to turn your antivirus off:
- Allow only that file. In your antivirus quarantine or history, restore or allow only
Instalar-Fold-1.0.5.exe. In Windows Security it is under “Virus & threat protection” › “Protection history”. - Before opening it, check its fingerprint. Open PowerShell from the Start menu and type
(Get-FileHash "$HOME\Downloads\Instalar-Fold-1.0.5.exe").Hash. You should get the SHA-256 fingerprint above (upper or lower case does not matter). - If it does not match, or you have any doubt, do not open it. Delete it and write to us at CEO@foldburnao.com: we will look at it with you.
What changes in each version. Fold updates itself, and it keeps a copy before each new version.
