What changed, release by release

• NewDeskCalc Verify shows the document next to the check: if printed figures differ, a pinned tape on the left shows them as printed — wrong lines in red, figures that only follow from them in yellow. Both tapes scroll together. If everything matches, the check tape gets a green frame (red when figures differ).

Left: the invoice as printed — one line total misprinted (red), discount, VAT and total follow from it (yellow). Right: DeskCalc’s calculation. How DeskCalc Verify works

• NewDeskCalc Verify: an AI assistant (Claude Desktop, Codex) hands over the figures of an invoice, a stack of receipts, a bank statement or a table as a labelled tape. You check and correct every line in DeskCalc and press Confirm — only then does the AI get the result. It checks VAT, quantity × price, discounts, mixed VAT rates (one block per rate with a GT line), carry-overs and cross-footing, and can save an audit record as PDF.
• NewA VAT line can have its own rate (e.g. 10 % while 20 % is set); the rate is saved with the tape.
• NewThe Microsoft Store version can be started from the command line (deskcalc).
• NewDeskCalc reads the tape aloud when the speech option is on (accessibility).
• ChangePrintouts and PDF export of the registered version no longer carry a DeskCalc footer; the free version prints a small “deskcalc.com”.
• FixVAT included in an amount could be off in the last digits (120 incl. 20 % gave 99.999996 instead of 100.00).
• FixSilent setup (/S, as used by winget) now replaces a running or previous DeskCalc reliably; “Apps & Features” shows version and publisher.

• NewSave all open tapes together as a project file (.dcp) and restore them.
• NewOverlay window for passing values to a new tape.
• NewA column of numbers captured as text — e.g. Word or Excel cells, or other selected numbers — can be pasted straight into the tape: exact, with no recognition errors.

• NewThe whole financial wizard — interest, loan, disagio and the business-analysis dialogs — now appears in English on English systems.
• FixMost finance and business dialogs now print a clean text report instead of a dialog snapshot — readable on high-resolution screens.
• FixThe loan calculator no longer crashes on incomplete input.
• FixThe “Memorized Text List” dialog and the startup dialog showed in German on English installs — now translated.
• NewAutomation command-line switches for scripts and other programs: /resultfile <file> writes the current result to a text file (a return channel into a running DeskCalc); /show brings DeskCalc to the front; /save [file] saves the current tape; /excel exports to Excel; /print prints silently.

• NewThe Excel export now carries formulas instead of formatted text only — you can keep calculating with the tape in Excel.
• NewTwo tapes side by side — pin one and compare, or take a calculation over into the active tape.
• UpdateDouble-clicking a tape tab opens the naming dialog, the same as a right-click.
• FixThe mark for continuing with the last result is now transparent — it used to sit on a white box, which showed on the PostIt tape export.

• NewRedrawn icon set for the ribbon — single colour, following the selected theme.
• NewColour only where it tells two commands apart: Excel green, Word blue, M+ green, M− red.
• NewRedesigned calculator keys — rounded, larger, in the colours of the theme.
• NewRight-hand keypad rearranged, now with Backspace, CE, C and +/−.
• NewRibbon and Quick Access toolbar alternate — collapse the ribbon and the toolbar appears.
• NewQuick Access toolbar below the ribbon, preset with New, Open, Save, New Tab, Excel, PostIt and Click & Calc.
• UpdateNew installations start with the “Light” theme.
• UpdateWin + Shift + A is the shortcut for Click & Calc.

The big release. The headline change is what happens after you press Copy — read the full version 11 story.

• NewPaste the tape and it stays a table: the clipboard now carries HTML, an RTF table, plain text and an image at once. Word, Excel and WordPad keep the real columns, the font and colours, the red negatives and your position labels.
• NewClick & Calc works on its own — no PowerToys required. It reads numbers from any window, picks up the decimal separator from the scanned text (both 1,234.56 and 1.234,56), and can sit on the Quick Access toolbar.
• NewThe tape as a picture now carries its own colours, and pasting into Adobe PDF Pro and Creator is supported — at the right size.
• UpdateEvery dialog follows the theme you chose, light or dark; the dark themes were reworked. On Windows 11 the title bar is dark and the corners are rounded.
• NewEach tape shows its result in its own tab header — read every total at a glance.
• NewA taskbar jump list: new tape, Click & Calc, Copy as image, and your most recent tapes.
• NewSpanish, French and Italian added or brought up to date.
• FixENTER and ESCAPE now behave correctly when you finish editing a text on the tape.
